I am back, and finally had some time to look at your script. Very well done. Your script produces some very classy looking logos. I have few suggestions however. First... I would do the rounded corners AFTER creating the gradient overlay of the two images. ASIDE: I recently added an example for doing such overlays into IM examples, though did so before looking at your script. It should appear in IM examples at http://imagemagick.org/Usage/photos/#overlap in the next day or so. Second the way you create the overlay involved converting green to transparent. This is a bad idea as you essentually create a aliased on/off masking image to round the corners. If you look at the corners of the images you created you can see a distinct staircase type of effect. What you want to do is to try and make a smooth aliased mask image. That is draw either a filled rounded rectangle which is either black on a white background or white on black. This you then use to mask the image using -compose CopyOpacity, so that the smooth looking corners (involving grey intermediate pixels) are translated into a smooth corner of the logo (using semi-transparent pixels). And Third, why you keep the right edge square, I think it make look nicer of you had rounded corners there too. This however is optional.
